Description

  The present application relates to the communication field, and in particular, to a resource reconfiguration method, a base station, and a user equipment.

  When it is necessary for user equipment (User Equipment, UE for short) to perform uplink communication with the cell of a base station, it is necessary to acquire the timing advance (Time Advance, TA) of the cell. The TA from a specific UE to a specific cell changes with changes in factors such as the location of the UE, so after every acquisition of the latest TA from the base station, the UE Start or restart TAT). When TAT times out, the UE considers that the already acquired TA is no longer valid, thus releasing the uplink resource configuration and terminating all uplink transmissions except for random access requests, which is unnecessary. Uplink interference is avoided. If the TA from the UE to multiple cells is the same, the multiple cells belong to the same TA group. Cells belonging to the same TA group share the same TAT. In response to the TAT maintained by the UE, the base station also maintains a timer. Each time after sending the latest TA to the UE, the base station also correspondingly starts or restarts a timer maintained by the base station, so the base station is maintained by the base station. By using the timer state, the corresponding TAT state maintained by the UE can be inferred.

  When the UE needs to send new uplink data to the base station, the UE sends a scheduling request (SR) to a specific cell of the base station to request uplink resources. If the base station does not respond to the SR, the UE can repeatedly transmit the SR, but cannot exceed the maximum number of repetitions. When the number of times that the UE transmits an SR reaches the maximum number of repetitions, the UE considers that an SR failure has occurred. If the UE detects an SR failure, the UE releases the uplink resource configuration and initiates a random access request to the base station.

  A physical uplink control channel (PUCCH) resource is also required for the UE to transmit the SR. In most cases, the base station configures a PUCCH resource for transmitting the SR and transmits it to the UE in advance. However, since PUCCH resources are relatively scarce, depending on conditions such as the uplink service of the UE, the base station cannot preallocate PUCCH resources for transmitting SRs to the UE.

  Uplink data has arrived at the UE, but the UE detects that the TAT has timed out, or detects that an SR failure has occurred, or that there is no PUCCH resource available for SR transmission After detection, the UE initiates a contention based random access process to the base station. In this process, the UE obtains an updated TA and uplink grant (Uplink Grant, UL Grant, UL grant), and the uplink grant corresponds to the assigned uplink resource. The UE can transmit uplink data or control information such as a buffer status report (BSR for short) by using uplink resources. The base station can then send a reconfiguration message to the UE, where the message includes an uplink resource configuration, which includes, among other things, a scheduling request (SR) configuration, a sounding (Sounding) It includes at least one of a reference signal configuration and a channel quality indicator (CQI) reporting configuration. The UE transmits SR, sounding, and CQI to the base station according to the uplink resource configuration. In a new type of network deployment, the UE can communicate simultaneously with more than two base stations, one base station is called the primary base station and the other base station is called the secondary base station. The primary base station and the secondary base station may be connected.

  According to the prior art, the TAT of the secondary base station times out or the UE's SR failure occurs at the secondary base station, or the UE has PUCCH resources to transmit the SR to the secondary base station If it detects no, the UE can initiate a contention based random access process only to the secondary base station, and then the secondary base station can send a reconfiguration message to the UE. However, prior art secondary base stations may not have a reconfiguration function, which may cause the reconfiguration process to fail.

  In addition, the contention-based random access process used by the UE has a relatively long delay time and easily fails due to collisions, thereby delaying the transmission of uplink data and hindering the user experience .

The information includes at least one of an identifier of the user equipment, a cell identifier of the secondary base station required to be a resource reconfigured by the user equipment, and a reason for requesting reconfiguration. 98. A user device according to any one of 1 to 97. The reason for requesting reconfiguration is
The timing advance timer TAT has timed out, the scheduling request SR has failed, the physical uplink control channel PUCCH resource for transmitting the SR is not in the secondary base station, and the user equipment transmits the uplink data to the second 96 or used to indicate information of one of the need to transmit to a secondary base station and the secondary base station needs to transmit downlink data to the user equipment 98. User device according to 98. A base station used as a secondary base station,
A transceiver configured to transmit and receive signals;
A processor, the processor comprising:
Determining that the resource corresponding to the secondary base station needs to be reconfigured for the user equipment;
Controlling the transceiver to transmit a first message to a primary base station, whereby the primary base station initiates reconfiguration of the resource corresponding to the secondary base station for the user equipment; A base station configured to perform. The processor that the resource corresponding to the secondary base station needs to be reconfigured for the user equipment;
When the transceiver receives a random access request message sent by the user equipment, the processor determines a reconfiguration of the resource corresponding to the secondary base station for the user equipment, or the processor When detecting that the timing advance timer TAT of the user apparatus corresponding to the secondary base station has timed out, the processor retransmits the resource corresponding to the secondary base station for the user apparatus. 101. The base station according to claim 100, wherein the base station is determined in a manner of determining a configuration.   After determining that the resource corresponding to the secondary base station needs to be reconfigured for the user equipment, the processor is configured for the user equipment and corresponds to the secondary base station The uplink resource configuration information to be transmitted is controlled by the transceiver to the primary base station, whereby the primary base station transmits the uplink resource configuration information to the user equipment. base station. The uplink resource configuration information is
104. The base station of claim 102, comprising at least one of scheduling request configuration information, sounding reference signal configuration information, and channel quality indicator report configuration information. The first message is:
The information includes at least one of an identifier of the user equipment, a cell identifier of the secondary base station required to be a resource reconfigured by the user equipment, and a reason for requesting reconfiguration. 104. The base station according to any one of 1 to 103. The reason for requesting reconfiguration is
TAT timed out, scheduling request SR failed, physical uplink control channel PUCCH resource for transmitting SR is not in the secondary base station, the user equipment sends uplink data to the secondary base station 105. The base of claim 104, used to indicate information of one of: need to transmit to said user, and said secondary base station needs to transmit downlink data to said user equipment Bureau.
